Improvement in sash-fastenings



NITED STATES- PATENT OFFICE.

IMPROVEMENT IN SASH-FASTENINGS.

Specication forming part of Letters Patent No. 55,298, dated June 5, 1866.

To'alZ whom "it may concern.-

Be it known that I, WILLIAM W. HosFoR-D, of New Britain, county ofv Hartford, and State of Connecticut, have invented certain new and useful Improvemen ts in Sash Supports or Fasteners 5 and I do hereby declare that the same is described and represented in the following specification and drawings, so as to enable others skilled in the art to, make and use the same. v

I will therefore proceed to describe by referring to the drawings, in which the same letters of reference refer to like parts in each of the iigures.

The nature of this improvement will be understood from the specication and drawings.

The object desired to be attained thereby is to produce a cheap, simple, and eficient art-icle, which shall be tasteful in its appearance, cheap and labor-saving in preparing for market, effective and desirable for fastening or holding the sash in position, and not liable to get out of order.

In the Iaccompanying drawings, Figure l is a face view, represented as being secured upon the stile of a sash or upon thejamb of a window. Fig. 2 is a sectional view. Fig. 3 is an under-side view .of eccentric cam e, having an arm orlever, o, for turning the cam in the desired direction. Fig. 4 is a face-plate, to or upon which the cam is secured, and by which the whole fastener is secured to the sash or janib.

The face-plate a is made of any desirable shape and coniguratiomhaving lugs b formed on the under or back side, which are designed to be let into the wood to hold the plate in its proper position, so that (with the aid of screws in the common way) they shallbe held firmly to the jamb or sash. Upon the face side of this plate is provided a hub, c, into which is fitted the screw d, which serves as a fulcruin for the cam e to play upon and to hold it firmly to the plate a.

71l are protuberances formed on the face side of the plate a, having depressions which form seats,in or upon which the ends of the spring z' take its bearing, and is held therein by the arm o. The spring' i is formed with a prominence, i', near its center, the object of which is to enter the depression i in the cam k,`to hold the cam e in an inactive or locked position when not wanted for holding or fastening the window.

The pin or screw holes of the cam e are made eccentric with the outside surface or bearingsurface thereof, so that as the cam is turned by means ofthe arm or levero in either direction it will bind against thejamb or sash, and thus hold the window in either a raised or closed position.

Thus it will be seen that by the use of this improvementthe window may be raised or lowered freely without hinderance from the fastening until it said is required, and when raised or lowered it will be held firmly by simply turning the arm o so as to bring the cam e into action. That is, when the sash is raised, by turning the lever or arm 0 up it will bring the face-surface of the cam e against the jamb or sash, when the harder the pressure the tighter it will hold. So, when the window is closed, by turning lever or arm 0 in the opposite direct-ion, the window will be fastened.

This improvement is susceptible of various modifications in its size and style without changing the principle of its operation. I'

believe I have thus shown the nature, construction, and operation of this my improvement, so as to enable others skilled to make and use the same therefrom.

What I claim, therefore, and desire to secure by Letters Patent, is-

The combination of the cams 7c e with the plate a, spring i, and arm o, arranged and operating substantially as and for the purpose described.
